-STMicroelectronics STM32 SPI Controller
-
-The STM32 SPI controller is used to communicate with external devices using
-the Serial Peripheral Interface. It supports full-duplex, half-duplex and
-simplex synchronous serial communication with external devices. It supports
-from 4 to 32-bit data size. Although it can be configured as master or slave,
-only master is supported by the driver.
-
-Required properties:
-- compatible: Should be one of:
-  "st,stm32h7-spi"
-  "st,stm32f4-spi"
-- reg: Offset and length of the device's register set.
-- interrupts: Must contain the interrupt id.
-- clocks: Must contain an entry for spiclk (which feeds the internal clock
-	  generator).
-- #address-cells:  Number of cells required to define a chip select address.
-- #size-cells: Should be zero.
-
-Optional properties:
-- resets: Must contain the phandle to the reset controller.
-- A pinctrl state named "default" may be defined to set pins in mode of
-  operation for SPI transfer.
-- dmas: DMA specifiers for tx and rx dma. DMA fifo mode must be used. See the
-  STM32 DMA bindings, Documentation/devicetree/bindings/dma/stm32-dma.txt.
-- dma-names: DMA request names should include "tx" and "rx" if present.
-- cs-gpios: list of GPIO chip selects. See the SPI bus bindings,
-  Documentation/devicetree/bindings/spi/spi-bus.txt
-
-
-Child nodes represent devices on the SPI bus
-  See ../spi/spi-bus.txt
-
-Optional properties:
-- st,spi-midi-ns: Only for STM32H7, (Master Inter-Data Idleness) minimum time
-		  delay in nanoseconds inserted between two consecutive data
-		  frames.
-
-
-Example:
-	spi2: spi@40003800 {
-		#address-cells = <1>;
-		#size-cells = <0>;
-		compatible = "st,stm32h7-spi";
-		reg = <0x40003800 0x400>;
-		interrupts = <36>;
-		clocks = <&rcc SPI2_CK>;
-		resets = <&rcc 1166>;
-		dmas = <&dmamux1 0 39 0x400 0x01>,
-		       <&dmamux1 1 40 0x400 0x01>;
-		dma-names = "rx", "tx";
-		pinctrl-0 = <&spi2_pins_b>;
-		pinctrl-names = "default";
-		cs-gpios = <&gpioa 11 0>;
-
-		aardvark@0 {
-			compatible = "totalphase,aardvark";
-			reg = <0>;
-			spi-max-frequency = <4000000>;
-			st,spi-midi-ns = <4000>;
-		};
